In a small saucepan, whisk together the pureed strawberries, sugar, cornstarch and water.
Bring to a boil and continue to whisk for about 3 minutes as it thickens. Remove from the heat to allow to cool.
Cut fresh strawberries into quarters to measure 4 cups. Set aside
Once cooled, layer the strawberries in the bottom of the pie crust.
Pour the cooked/cooled filling over the top of the cut strawberries and spread out to fill in crevices.
Chill in the refrigerator for 2-3 hours before slicing. Use a sharp knife, not serrated, to cut through fresh strawberries in pie. Top with whipped cream,
